In wireless communications for multi-users, a station may receive a trigger frame including a transmitter address field. When the trigger frame is a multi-user request-to-send (MU-RTS) frame eliciting clear-to-send (CTS) frames from a plurality of stations, the station transmit a CTS frame including a first receiver address field in response to the trigger frame. The first receiver address field may be set equal to the transmitter address field. When the trigger frame elicits data frames from a plurality of stations, the station transmit a data frame including a second receiver address field in response to the trigger frame. The second receiver address field may be set to a destination address. Other methods, apparatus, and computer-readable media are also disclosed.

A method for wireless communication performed by a sensing user equipment (UE) includes identifying resource availability during a sensing window. The method further includes receiving a request to share resource information with a transmitter UE. The method still further includes determining a sharing condition is satisfied. The method also includes sharing the resource availability with the transmitter UE based on satisfying the sharing condition.

A PUCCH collision processing method and a terminal are provided, and the method includes: transmitting, in a case that a first PUCCH and a second PUCCH overlap in a first slot, one of the first PUCCH and the second PUCCH within the first slot according to a configuration of at least one of the first PUCCH and the second PUCCH, wherein, the first PUCCH is configured as multi-slot PUCCH repetition transmission, and a carried content in the first PUCCH includes one of Channel State Information CSI and a Scheduling Request SR, the second PUCCH is configured as single-slot or multi-slot PUCCH repetition transmission, and a carried content in the second PUCCH includes one of CSI and an SR; the first slot is one or more slots.

A method for WTRU autonomous resource selection may comprise receiving a TX resource pool for D2D communication from a base station. The WTRU may sense one or more resources of the TX resource pool and determine resources for transmission of control information and D2D data, based on the sensing. The WTRU may then transmit, to another WTRU, the control information and the D2D data on the determined resources.

Wireless communication between a user equipment (UE) and a base station may occur on unlicensed spectrum. When wirelessly communicating on unlicensed spectrum, there is an expectation that there may be interference from others devices also transmitting on the same resources in the unlicensed spectrum. Systems and methods are therefore disclosed that aim to facilitate wireless communication in unlicensed spectrum. In some embodiments, systems and method are disclosed that are directed to the transmission of uplink control information (UCI) in unlicensed spectrum. The UCI may be or include hybrid automatic repeat request (HARQ) feedback. The HARQ feedback may correspond to a downlink data transmission that was also sent on unlicensed spectrum.

Provided in the present disclosure are an uplink control information transmission method and device. The method includes determining that a first transmission resource corresponding to uplink data to be transmitted and a second transmission resource corresponding to uplink control information to be transmitted overlap in a time domain. The method also includes transmitting the uplink control information on the second transmission resource and terminating transmission of the uplink data on the first transmission resource.

Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining application timing for path loss reference signals (PL RS). For example, the application timing is determined by determining an applicable time for a medium access control control element (MAC-CE) based PL RS for physical uplink control channel (PUCCH) and other uplink transmissions. A user equipment (UE) may receive a MAC-CE indicating a PL RS update and determine the applicable time for applying the PL RS update based on one or more conditions. The applicable time may be a period after acknowledgement of the MAC-CE or correspond to a certain measurement sample of a new PL RS a period after acknowledgement of the MAC-CE. The one or more conditions may relate to a total configured number of PL RS for the UE, whether a MAC-CE based PL RS activation feature is enabled, among others.

A wireless communication terminal operating as a Station (STA) is provided. The wireless communication terminal includes a wireless transceiver and a controller. The wireless transceiver performs wireless transmission and reception to and from an Access Point (AP). The controller receives a trigger frame including a Resource Unit (RU) Allocation subfield which has one bit to indicate support of 320 MHz bandwidth from the AP via the wireless transceiver, determines a combination of RUs to be used in a Trigger-Based Physical layer Protocol Data Unit (TB PPDU) according to the RU Allocation subfield, and sends the TB PPDU for Uplink (UL) data transmission to the AP via the wireless transceiver in response to the trigger frame.

According to an embodiment of the present disclosure, a terminal may store a time correction value acquired from an RA response message during an RRC layer connection to a base station, receive, from the base station, an uplink resource allocation message including an uplink resource allocated to the terminal, after the RRC layer connection to the base station is released, and when an RRC layer connection to the base station is determined, establish the RRC layer connection to the base station without transmitting an RA preamble message, on the basis of the stored time correction value and the allocated uplink resource.
